Temporal resolution of hearing probed by bandwidth restriction

Web10 okt. 2009 · Chicago, IL. Given the Nyquist Theorem and the accepted notion that the top of the human hearing range is around 20 kHz, our theoretical sampling rate, if our hearing was digital, would be around 40 kHz. According to the Nyquist Theorem, dividing the sampling rate in half will yield the highest audible frequency in a digital recording. WebOur research, involving psychophysical testing of human subjects and neurophysiological modeling of the hearing system, shows the inapplicability of the usual time-frequency relationship and the ability of humans to discern 5 microseconds timing alterations.
